If you freeze a potato for a day or so and thaw it, will it continue to grow roots? If not, why not? If so, why didn’t freezing eliminate this potential?
My bro just chucked one of them in the freezer, we’ll see for sure in a little while, but just wanted to ask the Dopers first! Thanks.
Btw, he vaccum sealed it to prevent freezer burn or any other complications.
Just because the little spud got tossed doesn’t mean some of us aren’t interested anyway.
Will a frozen potato still grow eyes when thawed?
Probably not. Freezing tends to break cell membranes. That tends to turn frozen living things into nonliving goosh upon thawing. Plants are a little hardier than animals, having a cellulose based cell wall and all, but that wall is thinnest in rapidly differentiating tissue, like spud eyes.
If preserving potato viability were as easy as tossing a spud into the freezer, there’d be no need for articles like this:
Advances in Potato Cryopreservation by Vitrification
Potatoes are natives of mountainous areas that do experience hard frosts, however, the tubers are protected by being underground. I’m inclined to say that a live potato that has been completely frozen solid will probably suffer extensive damage at a cellular level due to the water inside the cells expanding and causing them to burst. It’s possible that some individual cells or small islands of cells in the potato could survive the process, but rot is going to set in pretty quickly after thawing and this would probably overwhelm any remaining living tissues.
So, if you pair them back up, do they retain viability?
This thread reminds me of my Grandfather’s potato cellar. Back before refrigerators that is how people kept potatoes for use year around. It was a dank place with a smell that I’m sure only potato cellars have.
As to whether frozen potatoes will sprout, I thought of the question “Would a frozen french fry sprout?” I doubt it. :dubious:
What happens to potato plants over the winter? Do they sprout from potatoes that have been in the frozen ground?
According to this , Solanum tuberosum is a perennial, hardy to zone 8.
Winter low temperatures in zone 8 only get down to -12 to -7 C (10 to 20 F).
According to the US Zone Map, that corresponds to the climate of southern Georgia.
There’s not much chance of overwintering in most of the US.

That potato is a sad representation of its former self! Squishy on the outside, little sprouts are dead and gone. Should I eat it!?
If you’re quick about it. Squishy raw potatoes are an excellent substrate for mold growth.
